FIELD OF THE INVENTION

The present invention relates to 4-[(3-ethynylphenyl)amino]-6,7-benzo-12-crown-quinazoline hydrochloride and new crystalline forms thereof, the present invention also relates to methods for synthesizing this compound, pharmaceutical compositions containing this compound, use of the compound for the treatment of cancer and the relevant intermediates therefor.

BACKGROUND OF THE INVENTION

Tyrosine kinase receptors are trans-membrane proteins that, in response to an extracellular stimulus, propagate a signaling cascade to control cell proliferation, angiogenesis, apoptosis and other important features of cell growth. One class of such receptors, epidermal growth factor receptor (EGFR) tyrosine kinases, are over-expressed in many human cancers, including brain, lung, liver, bladder, breast, head and neck, esophagus, gastrointestinal, breast, ovary, cervix or thyroid cancer.

EGFR is expressed in many types of tumor cells. Binding of cognate ligands (including EGF, TGFα (i.e., Transforming Growth Factor-α) and neuregulins) to the extracellular domain causes homo- or heterodimerization between family members; the juxtaposition of cytoplasmic tyrosine kinase domains results in transphosphorylation of specific tyrosine, serine and threonine residues within each cytoplasmic domain. The formed phosphotyrosines act as docking sites for various adaptor molecules and subsequent activation of signal transduction cascades (Ras/mitogen-activated, PI3K/Akt and Jak/STAT) that trigger proliferative cellular responses.

Various molecular and cellular biology and clinical studies have demonstrated that EGFR tyrosine kinase inhibitors can block cancer cell proliferation, metastasis and other EGFR-related signal transduction responses to achieve clinical anti-tumor therapeutic effects. Two oral EGFR kinase inhibitors with similar chemical structures are Gefitinib (Iressa; AstraZeneca), approved by the U.S. FDA for advanced non-small cell lung cancer in 2003 (and later withdrawn), and Erlotinib Hydrochloride (Tarceva; Roche and OSI), approved by the U.S. FDA for advanced non-small cell lung cancer and pancreatic cancer treatment in 2004.

A powder X-ray diffraction pattern method was used to characterize the structure of Crystalline Form IV; see FIG. 4 (TGA Instrument: DSC204 (NETZSCH company)). The TGA result indicated that each molecule of Icotinib hydrochloride Crystalline Form IV contained 0.158 molecules of crystalline N,N-dimethylformamide.

Efficacy Tests Test 1: Inhibition and Selectivity of the EGFR Tyrosine Kinase by Icotinib Hydrochloride Crystalline Form I by Polyacrylamide Gel Electrophoresis

Method: This method is based on the ability of protein kinases to catalyze substrate phosphorylation; radioisotope ³²P-labeled ATP (³²P-γ-ATP) is utilized in the reaction system to radioactively tag the protein substrate with ³²P. After separation and isolation of the protein substrate by polyacrylamide gel electrophoresis, the intensity of the radioactive ³²P-labeled protein substrate is recorded.

The EGFR tyrosine kinase (2.4 μg/μl, 14.5 units/μg, Sigma) and Crk (EGFR substrate, 32 ng/μl) were mixed in 25 μl of kinase reaction buffer. The kinase reaction buffer included 1 μM of non-isotope labeled-ATP. The above-mentioned mixture contained different concentrations of Icotinib hydrochloride Crystalline Form I (0, 0.5, 2.5, 12.5, and 62.5 nM). The mixture was incubated on ice for 10 min, and 1 μCi of ³²P-γ-ATP was then added. After incubation at 30° C. for 20 min, SDS (sodium dodecyl sulfate) sample buffer was added, and the mixture was boiled in a 100° C. water bath for 4 min. The samples were separated by 10% SDS-PAGE. After vacuum drying of the polyacrylamide gel, the intensity of radioactively labeled proteins were measured and recorded using a Phosphorimager (Molecular Dynamics Inc.). The signal was quantitatively analyzed utilizing ImageQuant software. The degree of Crk substrate phosphorylation was used to estimate the activity of the kinase.

Inhibition (%)=(1−kinase activity of the test group/kinase activity of control group)×100%

Results:

(1) Icotinib hydrochloride Crystalline Form I inhibited EGFR tyrosine kinase activity in a dose-response dependent relationship. When the concentration of Icotinib hydrochloride Crystalline Form I was 0.5, 2.5, 12.5 and 62.5 nM, the inhibition rates of EGFR kinase activity were 20.5, 36.6, 63 and 87.6%, respectively. From the dose-response curve, the IC₅₀ of Icotinib hydrochloride Crystalline Form Ito inhibit EGFR kinase activity (the concentration of the inhibitor when 50% of the activity was inhibited) was 5 nM, similar to the products marketed abroad.

(2) In order to study the selectivity of Icotinib hydrochloride Crystalline Form I for EGFR kinase inhibition, the ability of Icotinib hydrochloride Crystalline Form I to inhibit EGFR and Arg (abl-related gene) tyrosine kinase activities and Crk substrate phosphorylation was compared in parallel using the same methodology. The concentration of 62.5 nM of Icotinib hydrochloride Crystalline Form I did not inhibit the Arg kinase but did inhibit the EGFR kinase by 97% demonstating the selectivity of the Icotinib hydrochloride Crystalline Form I for the EGFR kinase.

The results described above show that Icotinib hydrochloride Crystalline Form I is a sensitive and selective EGFR kinase inhibitor.

Test 2: Inhibition of EGFR-Mediated Protein Phosphorylation by Icotinib Hydrochloride Crystalline Form I at the Cellular Level

Methods: The experiment utilized a high EGFR-expressing cell line, A431 (human epidermoid carcinoma). A431 cells in logarithmic growth phase were seeded into 12-well cell culture plates (5×10⁵ cells/well); the cells were grown in DMEM cell culture medium (Gibco Company) containing 10% fetal calf serum (FCS) at 37° C. in 5% CO₂ for 18 hours. The cells were washed twice with PBS buffer, and DMEM without FCS was then added. After incubating for 18 hours, Icotinib hydrochloride Crystalline Form I in dimethyl sulfoxide (DMSO) was added to individual wells at final concentrations of 0, 10, 50, 250 or 1000 nM. After incubating at 37° C. for 2.5 hours, 100 ng/ml of EGF was added to stimulate the cells for 5 minutes. Cells were then extracted in the presence 1 mM vanadate (inhibits dephosphorylation) to collect total cellular proteins, and proteins were resolved by 10% SDS-PAGE and transferred to nitrocellulose. Following detection of phosphorylated proteins with anti-phosphotyrosine antibodies (PY99 and 4G10, Upstate Biotech) and visualization with a horseradish peroxidase-labeled second antibody (Transduction Laboratories, Inc.) and ECL chemiluminescence (Amersham Corp.), bands were quantified by densitometry. Membranes were then stripped and incubated with anti-EGFR antibodies to compare amounts of EGFR in cells exposed to different concentrations of Icotinib hydrochloride Crystalline Form I as an internal control.

Inhibition (%)=(1−kinase activity of the test group/kinase activity of control group)×100%

Results: In A431 cells, Icotinib hydrochloride Crystalline Form I inhibited EGF-induced, EGFR tyrosine kinase-mediated intracellular protein tyrosine phosphorylation by 5.4, 52.9, 61.9 and 63.7% at concentrations 10, 50, 250 and 1000 nM, respectively. The median effective concentration (EC₅₀) was approximately 50 nM. The results also demonstrated that EGFR expression was not significantly different between cells exposed to different concentration of Icotinib hydrochloride Crystalline Form I, suggesting that the drug did not alter EGFR expression but it only inhibited EGFR kinase activity.

Test 3: Growth Inhibition In Vitro of Human Tumor Cell Lines by Icotinib Hydrochloride Crystalline Form I

Tumor cell lines: A431 human epidermoid carcinoma, A549 human non-small cell lung cancer, BEL-7402 human hepatoma, BGC-823 human gastric adenocarcinoma, HCT8 human colon cancer, H460 human lung adenocarcinoma, KB human epidermoid carcinoma.

Method: Cells (˜2×10³) were seeded in 96-well plates in 200 μL of RPMI1640 cell culture medium supplemented with 10% FBS. After 24 hours at 37° C. and 5% CO₂, the medium was replaced in quintuplicate wells with medium containing Icotinib hydrochloride Crystalline Form I dissolved in DMSO and then serial diluted, yielding final Icotinib concentrations of 0.05-300 μM. DMSO concentrations were less than 0.1% at the highest drug concentrations. Cells were incubated in medium alone with 0.1% DMSO as a negative control. Following a 96 hr incubation, the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium] colorimetric assay was performed using a microplate reader (reference wavelength 450 nm, detection wavelength 570 nm). The logarithm of drug concentration on the inhibition rate was linear, and the half inhibitory concentration of the drug (IC₅₀) was obtained.

Result: As shown in Table 3, in vitro growth inhibition by Icotinib hydrochloride Crystalline Form I on human tumor cells, including high EGFR-expressing A431 cells, was dose-dependent. The A431 cell line was extremely sensitive, with an IC₅₀ of 1 μmol/L, followed by the gastric cancer cell line BGC823, human non-small cell lung cancer cell line A549 and human lung adenocarcinoma cell line H460 with IC₅₀'s of 4, 12 and 16 μmol/L, respectively. Icotinib hydrochloride Crystalline Form I had low activity against HCT8, BEL-7402, and KB tumor cells.

Test 4: Tumor Inhibition by Icotinib Hydrochloride Crystalline Form I on Human a Tumor Xenograft in Nude Mice

This was a preliminary study to compare Icotinib hydrochloride Crystalline Form I with erlotinib hydrochloride on inhibition of human A431 (human epidermoid carcinoma cell line) xenograft tumor.

Methods: The high EGFR-expressing human A431 (human epidermoid carcinoma cell line) cell line was selected for the xenograft study.

Tumor transplantation method: A431 human epidermoid cancer cells were inoculated subcutaneously in the right armpit of BALB/C nude mice to generate tumor nodules. These nodules were harvested, cut into 6 mm³ blocks for routine inoculation and implanted into each mouse for the study. When tumors reached approximately 20 mm³ in size (6-7 days), the animals were randomly divided into 4 groups of 6-9 animals/each group and body weights were recorded. The groups consisted of a control group (no drug treatment), an erlotinib hydrochloride treatment group (200 mg/kg) and high and low dose Icotinib hydrochloride Crystalline Form I treatment groups (200 and 50 mg/kg). Drugs were administered by oral gavage once daily; dosing frequency depended on the individual case for tumor growth. Tumor volume [tumor volume (V)=tumor size (L)×short diameter of tumor (S)²/2] was measured using calipers once every 3 days. The animals were sacrificed 24-hour after the last drug administration and weighed. The tumor was removed and weighed to accurately calculate the tumor size. All group data was analyzed using the t test. If the p value was <0.05, it was considered to be statistically significant.

Efficacy determination: tumor inhibition rate=[1−treatment group mean tumor weight (T)/control group mean tumor weight (C)]×100%

The results showed that Icotinib hydrochloride Crystalline Form I given orally in the A431 xenograft mouse model had significant anti-tumor effects and a dose-response relationship. Efficacy results between Icotinib hydrochloride Crystalline Form I and erlotinib were comparable at 200 mg/kg, with erlotinib demonstrating modestly better tumor inhibition (77.6%) in this model than Icotinib hydrochloride Crystalline Form I (64.6%). However, toxicity was greater with erlotinib; 3 of 8 animals died after 5 days at 200 mg/kg necessitating a dose reduction to 100 mg/kg after a 9 day recovery period. Icotinib was reduced to 100 mg/kg at this point as well for consistency and comparability. No toxic effects were observed for the Icotinib group at either dose. At the experiment termination, animals in the erlotinib group had lost weight and appeared sluggish in contrast to animals in the Icotinib group that had gained weight and tolerated drug administration for an additional 9 days.

Test 5: Comparison of Icotinib Hydrochloride Crystalline Form I with Iressa™ Tablets on Inhibition of Human Tumor Xenograft Models in Nude Mice

Methods: Methodologies described in Test 4 were used in this study to compare the antitumor activities of Icotinib hydrochloride Crystalline Form I and Iressa™ tablets against the H460 human lung adenocarcinoma xenograft.

The results showed that when abrasive powders of Icotinib hydrochloride Crystalline Form I and Iressa™ tablets were administered by oral gavage once daily for 14 days, the H460 tumor inhibition rates of the high, medium and low dose groups (120, 60 and 30 mg/kg) of Icotinib hydrochloride were 52.0, 49.3 and 37.5%; the tumor inhibition rate of the Iressa™ group (120 mg/kg) was 38.3%. The Icotinib hydrochloride Crystalline Form 130 mg/kg group showed the same inhibitory activity against the H460 human tumor xenograft as the 120 mg/kg Iressa™ group while the two higher dose groups demonstrated greater inhibitory activity than the 120 mg/kg Iressa™ dose level. Toxicity appeared greater with Iressa™ than with Icotinib hydrochloride Crystalline Form I, with animals showing reduced body weight and appearing sluggish.

Pharmacology and toxicology experiments in Beagle dogs, mice, and rats using Icotinib hydrochloride Crystalline Form I were also conducted. The results showed that: Icotinib hydrochloride Crystalline Form I had low oral toxicity, no bone marrow toxicity and reversible liver toxicity. Safety pharmacological test results showed that Icotinib hydrochloride Crystalline Form I had no effect on respiration, blood pressure and circulatory function, and no effect on autonomic nervous system activity or the central nervous system. Additional toxicity testing results showed no teratogenic, mutagenic and reproductive toxicity.

In addition, non-clinical pharmacokinetic studies of Icotinib hydrochloride Crystalline Form I in Beagle dogs and rats were conducted. The results showed that Icotinib hydrochloride Crystalline Form I given orally was well absorbed with an absolute bioavailability of 27-62% in rats and dogs. The drug reached peak plasma concentrations (Tmax) in approximately 1 hour and was, eliminated mainly through fecal excretion and with a small portion through urine. Icotinib hydrochloride was widely distributed to various tissues, but was low in brain tissue, indicating the drug does not easily cross the blood-brain barrier. No significant induction effect on P450 enzymes in rat liver was found, and no inhibitory activity on drug metabolism enzymes was found for Icotinib hydrochloride Crystalline Form I.

Drugs and reagents: Icotinib (free base) and Icotinib hydrochloride crystalline forms I, II, III, and IV were ground to fine particles. The material content (purity) was not less than 99.0%. Sodium carboxymethyl cellulose was medical supply graded.

Experimental animals: Wistar rats, male and female, 150-220 g each.

Pharmaceutical preparation: Weigh the appropriate amount of each substance and add sodium carboxymethyl cellulose to 0.5%. Prepare a suspension at a final concentration of 3.5 mg/mL in water.

Administration and sample collection: Each suspension was administered orally to fasted Wistar rats at a dose equivalent to 35 mg/kg Icotinib hydrochloride in a dose volume of 10 ml/kg. Approximately 0.5-1.0 mL of blood was collected in heparinized tubes at time intervals of 1, 2, 3, 6, 10, and 24 minutes after drug administration, centrifuged, and plasma was collected and stored at −20° C.

After purification, samples were analyzed by high performance liquid chromatography. The chromatographic conditions utilized C18-silane bonded silica as stationary phase, 0.02 mol/L of sodium dihydrogen phosphate in acetonitrile (40:60, using sodium hydroxide solution to adjust pH to 5.0) as the mobile phase and a detection wavelength of 334 nm. The area under the concentration-time curve for each compound is shown in the table below.

The area under the The area under the concentration-time concentration-time curve (0-t) curve (0-infinity) Crystalline Form I 91.80 93.73 Crystalline Form II 88.28 90.77 Crystalline Form III 89.23 90.26 Crystalline Form IV 86.29 90.23 Free base 28.83 29.36

The above experiment showed that the area under the concentration-time curve (O-t) and area under the concentration-time curve (O-infinity) of Icotinib hydrochloride Crystalline Forms I, II, III, and IV were as high as approximately 3 times that of the free base form. Therefore, Icotinib hydrochloride Crystalline Forms I, II, III, and IV have significantly better relative bioavailability than the free base of Icotinib.
